In a method and device for compression of image data, in particular medical image data, the image data are initially compressed by means of a lossy compression method with a predetermined starting compression factor. The compressed image data are then analyzed to determine a quality value relative to a defined quality measure and the quality value is compared with a desired quality value predetermined relative to a defined quality measure. A new compression of the image data or further compression of the image data already compressed in a preceding step then ensues with a different compression factor and/or with a different compression method when the quality value deviates by a specific degree from the desired quality value.
